Development of NEMESI: A Multiparameter Library Generator Prototype for Industrial VVER and PWR Applications Based on APOLLO3®

A nuclear reactor's design and safety assessment relies on a calculation platform consisting of a series of calculations performed using different simulation tools, each dedicated to modeling a specific phenomenon. The European Union H2020 CAMIVVER Work Package 4 aims to establish lattice neutronics calculation methodologies for VVER and pressurized water reactor fuel assemblies employing the new-generation deterministic multipurpose neutron transport code APOLLO3®, developed by the CEA (Commissariat à l'Énergie Atomique et aux Énergies Alternatives) with the support of EDF (Electricité de France) and Framatome.
